What is the best probe option for measuring samples at over 12 pH?
Summary
Application specific probe recommendation.
Answer
The IntelliCAL PHC705A RED ROD High-Alkalinity pH Electrode (Product Number/Order Code PHC705A01) would be the recommended pH electrode to use in applications that have samples above 12 pH. It has specialized glass for increased accuracy and life expectancy in the highly alkaline samples. It also reduces risk of sodium interference at high pH.
